Jubilee advice needed.

Recommended Posts

Right Jubilee Phase Comparison.jpg

 

The red is first order filters, while the blue is Bessel 3rd order. 

 

I've been experimenting with lower order filters in the MEH and the Jubilees over the past couple of months and have found that they produce much flatter phase and group delay plots, and also sound significantly more "together" from a subjective viewpoint.

 

If you want to try first order filters on your Jubs or Jub-Khorns, let me know and I'll assist in any way that you want me to help. 

 

Note however that I'll be in and out of pocket for the next 2-6 weeks from today.

I would love to have a couple of those. They do not come up very often, I've heard nothing but good things about them.

 

Yes, I really like the MX-D1s.  I bought the first one new in 2007, because they seemed to be clearance priced from an online dealer, so I got the power amp of my dreams for an affordable price.  It did a great job of driving the 1974 La Scalas, and the upgrade in clarity and detail over the RX-V750’s amp section was amazing.  That AVR continued to power the centre and surround speakers (until it was replaced with a new 2016 RX-A2060), while the MX was connected to the RX-V’s Pre Out sockets.  

 

As one reviewer put it, it was as if the amp shone brighter lights on the stage, all the way to the back, so you could see/hear every instrument clearly, even the ones in the back that usually got lost in the mix somewhere and wound up nearly inaudible.  The very low noise floor helped bring out that low-level detail that I hadn’t been hearing.  Familiar songs sounded new and a bit different, but in a good way.  Going the other way, 500 clean watts of power per channel meant that my ears literally hurt before it would get to max volume.  It’s better to have more power than you need, instead of needing more power than you have, right?

 

A year later, a forum member in Seattle offered me a used MX, and a pair of  K510 horns with K-69-A drivers appeared in the Garage Sale section.  I took those events as omens, and soon found an EV Dx38 electronic processor at a guitar shop in California, so I had all the ingredients for a pair of 510 JubScalas.  Cool!

 

After picking up the second MX, while waiting for some of the other bits to arrive, I hooked it up to power the Heresy II surround speakers, and was surprised by how much more clear and solid they sounded.  Soon the other bits arrived, and the second MX became the bass amp, while the first one became the treble amp.  They work well together, of course.  It would be fun to find a third MX to power the surround speakers, which are now the original La Scalas, since they were replaced in the front with La Scala IIs (now 402 JubScala IIs) several years ago.

 

Wow, short story long, or what?  Hope that wasn’t too boring.

SOUNDS like a great plan, Chris.  

JUst so happens to be that next week I head to Hawaii ...til march 5th, so I will be out of the pocket, as well.

 

Let me 'fiddle' with the tuning on my 5.1 system and we can coordinate some email shuffling,  towards those inspirational FLATTENed phase curves.

 

MY question mainly is pertaining to me using two XILICA's for my 11 channels.

The system's 5.1 inputs/outputs are NOT formatted as they were before, ...when we were email each in the past for my 2.1 Jube setup  

 

The two XILICA 5.1 formatting :

 

Xilica # 1 INPUTS :

  • CH1 - SURROUND LEFT
  • CH2 - L E F T 
  • CH3 - R I G H T 
  • CH4 - SURROUND RIGHT

Xilica # 1 INPUTS :

  • CH1 - C E N T E R 
  • CH2 - open channel
  • CH3  - open channel
  • CH3  - S U B W O O F E R 

-------------------------------------------------------------------------------------------

Xilica # 1 OUTPUTs :

  • CH1 -Left Surr.    LF
  • CH2 -Left Surr.     HF
  • CH3 -L E F T         LF
  • CH4 -L E F T         HF
  • CH5  R I G H T      LF
  • CH6 -R I G H T      HF
  • CH7 -Right Surr.   LF
  • CH8 -Right Surr.   HF

Xilica # 2 OUTPUTs :

  • CH1 -C E N T E R  LF
  • CH2 -C EN T E R   HF
  • CH3 -
  • CH4 -
  • CH5 -
  • CH6 -
  • CH7 -
  • CH8 -S U B W O O F E R 

 

  *SHOULD we be concerned about this 5.1 Xilica formated configuration ?

No,

That was cool. The reason I commented on them is because there is one for sale on eBay. He wants $1650. I would need another, if one was ever to come up...

The effect that you mention--that they sounded better as they were turned up--is usually due to the ratio of reflected to direct energy flipping over as the SPL goes up. That's very easily controlled using room treatments, but pretty limiting in terms of what you can say about the performance of the loudspeaker if it's not yet accomplished. That's why I commented. That's not a particularly good way to judge loudspeakers (of any sort) and certainly not at the performance level as Jubs, IME. IIRC, the pair that you heard were very newly installed--as mentioned in advance of your visit on this forum that I remember reading--and perhaps without room treatments/sufficient floor coverings and/or dial-in time (i.e., the owner mentioned more than once that he's pretty busy and presently that time is in short supply to tinker with them).  I know about that situation as I had to learn about it myself over the years. 

@Chris A thanks for reminding me about this. I was listening for a bit this past weekend (imagine actually having time to listen:)) and was definitely made aware of what @Schu and you are saying. These speakers sound better at high volumes for sure. And what is needed to tame this is room treatments. I certainly cannot listen at 95 to 110 dB continuously.

ROOM TREATMENT is more than 50% of the equation. 

You can own the worlds greatest equipment and have the most professional tuning equipment, ...and you are still at WAR with the room.

 

Priority ONE after purchasing fine equipment... room treatment !

^ I definetely agree... its not that the jubilees did not sound good at lower db's E, I was just slightly underwhelmed based on some of the hyperbole used online in describing the speakers capabilities.

I was fully aware that more work was needed and that your beautiful set up was yet in its infancy. As soon as you dialed up the volume a smile was plastered across my face.

I’d grab it!  They retailed for $5000 USD when they came out in 2005, and Stereophile considered the MX-D1 a bargain at that price.  Maybe he’ll take $1400-1500.

Are you still in California? I'd love to hear LRC Jubes..

I am in the bay area. I will do auditions in about another year once I have a better permanent install for them and I don't have a crazy person next door.

Did I really just buy a Ferrari to drive around in a parking lot.

Aprilia (RSVR). Bike didn't have to leave the garage and my wife enjoyed it.....

So much this. I have some DIY panels that help immensely, but cant wait to have a final room I can really dial in. Carpet as well.

I just got the whole rsvr thing...

I don't know if you knew, but I had a NERA for several years.

Yup kept this tag as it kind of stuck since my days over at the AF1 Aprilia Forum. I had always dreamed of the Nera. Never got to see one in person. It was twice the price of the RSV if I can remember. I'll bet it becomes a collector someday.  I had the RSV 2004 grey with blue rims and then later traded for the 2007 factory R pictured here. Lots of track days on both bikes. Still think it was the best sounding bike out there if you put on a full system. I sold it in 2012 still miss it.

CONGRATULATIONs on their safe arrival !

~ I am curious of the size of the room (W x L X H )

 

~Have you prepped the room acoustically, ... before their arrival ?  

 

~Also, what components are you going to use ?

 

This is exciting, for sure.

  ~Enjoy the process.

Oh yes, countless threads to go through. I remember doing all the little mods I believe his name was Clarke? Was almost 14ish years ago? Removing weight from fly wheel, airbox mod flapper valve, the rear brake boiling to 5.1 and various mods to keep the clutch from getting air in it having to re-bleed. I remember Amari's posts as well. Never met in person as I was in MN, but read a lot of their suggestions. I think it was clarke that turned me to the tigcraft exhaust above. I did a few group buys as well, one was the smoked lenses above. Fun times, funny how small the world is.

Thanks! I have a few panels that are on the wall for temporary purposes. The new room slightly bigger than my old room, but opens up into the kitchen and no corner wall for imaging on one side.  I already had the L & R, for a year or so, but just got the center channel. I was using a DC-ONE, but recently bought a xilica instead as I needed more inputs/outputs. For the time being I'm using D75a amps. One per jube. Using same Pre as you 7703 Marantz. Source is FLAC from my NAS. 

 

Since we are planning to move either very soon or in about a year, I'm not going to spend too much time with customization. When we do move I will have a more permanant spot for many years. At that time I'm prepared to do all of the acoustic changes necessary, even if it means hammering or making walls. Horn subs will be added and so will my la scalas for surround.
